Trench Super Barrier Rectifiers from Diodes Incorporated Meet Efficiency Targets of Next Generation Chargers


PLANO, Texas --(Business Wire)--

Diodes (News - Alert) Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduces the first devices to be launched from Diodes' proprietary Trench SBR® (Super Barrier Rectifier) technology, which enables the stringent efficiency and temperature targets of next generation battery chargers to be achieved.

With their ultra-low forward voltage, low leakage current and cooler running characteristics, the new Trench SBRs meet the requirements of the charger output rectifier diode, easily coping with the shorter current pulses of 36kHz discontinuous mode charger designs.

Diodes Incorporated has initially introduced two devices: the 15A SBRT15U50SP5, for 10W smartphone chargers; and the 20A SBRT20U50SLP, for 12.5W tablet chargers. Such chargers are becoming smaller and thinner, and have efficiency and temperature targets that cannot be adequately met with traditional Schottky diode solutions.

SBRT15's forward voltage of 0.47V at 15A and SBRT20's forward voltage of 0.5V at 20A, coupled with an operating temperature of +90ºC, means conduction losses are minimized and charger efficiencies are increased. The devices' low reverse leakage currents at high temperatures, respectively 105mA and 100mA at +125ºC, also help minimize blocking mode losses.



The SBRT20U50SLP and SBRT15U50SP5 are the first rectifiers to be released from a complete portfolio of Trench SBR devices that span a reverse voltage range from 10V to 100V, current handling capability from 0.2A to 40A and a variety of different package options, including Diodes' space-saving PowerDI®123, PowerDI5 and PowerDI5060.
